java--构造器练习

题目： 

TriAngle类： 

package cn.sxt.arrays.ever;

public class TriAngle {
	private double base;
	private double height;
	
	public TriAngle() {
		
	}
	
	public TriAngle(double b,double h) {
		base = b;
		height = h;
	}
	public void setBase(double b) {
		base = b;
	}
	
	public double getBase() {
		return base;
	}
	
	public double getHeight() {
		return height;
	}
	
	public void getHeight(double h) {
		height=h;
	}
}

TriAngleTest类： 

package cn.sxt.arrays.ever;

public class TriAngleTest {
	public static void main(String[] args) {
		
		TriAngle t1 = new TriAngle();
		t1.setBase(2.0);
		t1.getHeight(2.4);
		
		System.out.println("base : "+ t1.getBase() + ",heigh : "+ t1.getHeight());
		
		TriAngle t2 = new TriAngle(5.1,5.6);
		System.out.println("base : "+ t2.getBase() + ",heigh : "+ t2.getHeight());
		
	}

}
